Efficiencies in data acquisition and transformation
Leyzack, Andrew
For many hydrographic offices, the introduction of electronic nautical charting has created two production streams: traditional (hardcopy) chart production and electronic (softcopy) or ENC (Electronic Nautical Chart) production. Until recently, survey technology and methodologies were designed to support the acquisition of data by providing deliverables suited to hardcopy chart production; additional data transformation including the creation of spatial objects and attributes were required to satisfy IHO standards for ENC production. Cartographic development has lead hydrographic offices to consider the use of a common digital data source for the production of both paper and electronic publications. Similarly, tools and methods have been developed which enable the hydrographic surveyor to support and perhaps expedite the process of common source chart production. This paper provides an overview of the processes and survey deliverables involved with capturing and transforming hydrographic features into spatial objects accordance with the IHO S-57 (Special Publication No. 57) standard.
